In my case, the rear muffler is now gone, but I left the center muffler (what some are calling a resonator) in place. I swear it has not increased the exhaust noise AT ALL. The only change I can detect is that the sound is now a little deeper and not unpleasant in the least. Even that change is very subtle.

I would not spend money on a new rear muffler if yours needs replacing. I would just have the shop replace your missing section with a straight pipe.
